Is reduced body growth of cod exposed to the gill parasite Lernaeocera branchialisa cost of resistance?
Three hundred and sixty‐nine cod Gadus morhua were individually marked and caged for 19 months. During this period, each cod was inspected several times for Lernaeocera branchialis . Growth in four groups of cod, identified by their infection history, were compared. During the caging, 79% of the cod...
